This curriculum is essentially the same as the US version of Math Mammoth Grade 3, only customised for the international audience in these aspects:

• The currency used in the money chapters in grades 1-3 is the Australian dollar. (The download versions for these grades also include the chapter on money for US, British, European, South African, Canadian, and New Zealand currencies.)
• The curriculum teaches the metric measurement units. Imperial units, such as inches and pounds, are not used.
• The spelling conforms to British international standards (British English).
• Page (paper) size is A4.
• Large numbers are formatted with a space as the thousands separator (such as 12 394). (The decimals are formatted with a decimal point, as is used in the US version.)

Third grade is a time for learning and mastering two (mostly new) operations: multiplication and division within 100. The student also deepens his understanding of addition and subtraction, and uses those in many different contexts, such as with money, time, and geometry.

The four main areas of study for third grade are:

1. Students develop an understanding of multiplication and division of whole numbers through problems involving equal-sized groups, arrays, and area models. They learn the relationship between multiplication and division, and solve many word problems involving multiplication and division (chapters 2, 3, and 9). They learn the multiplication tables, and learn how to use their knowledge of multiplication tables to solve basic division facts.
2. Students develop an understanding of fractions, beginning with unit fractions. They use fractions along with visual fraction models and fractions on a number line. They also compare fractions by using visual fraction models and strategies based on noticing equal numerators or denominators (chapter 10).

3. Students learn the concepts of area and perimeter. They relate area to multiplication and to addition, recognize perimeter as a linear measure (in contrast with area), and solve problems involving area and perimeter (chapter 7).

4. Students fluently add and subtract within 1 000, both mentally and in columns (with regrouping). They learn to add and subtract 4-digit numbers, and use addition and subtraction in problem solving (chapters 1 and 6).

Additional topics we study are time (chapter 4), money (chapter 5), measuring (chapter 8), and bar graphs and pictographs (in various chapters).

Please also see the table of contents for 3-A and 3-B (in the sample files), which will let you see the topics covered in more detail.

Some main features of Math Mammoth complete curriculum (Light Blue series) are:

• it focuses on understanding mathematical concepts
• uses clear explanations, lots of visual exercises and pattern exercises
• mastery oriented: concentrates at length on a topic, with very few topics per grade
• emphasizes mental maths and developing number sense
• very little teacher preparation needed

The downloadable version includes a worksheet maker (Internet access required) that lets you make extra practice worksheets for many of the topics in the curriculum.

In the download version, the chapter on coins (chapter 5) is included in seven currencies: US, Canadian, British, European, Australian, New Zealand, and South African money. You will automatically get all versions when you buy the Grade 3 Curriculum as a DOWNLOAD.

The PDFs in the download version are enabled for annotation. This means that if you prefer, the student can fill them in on the computer, using the typewriter and drawing tools in Acrobat Reader version 9 or greater.

## Manipulatives

Here is a list of manipulatives that are needed or recommended for grade 1:

1. A non-digital clock or other analog clock where you can turn the minute hand and the hour hand will move accordingly (for 3-A).
2. A ruler that measures in centimetres (for 3-B).
3. A measuring tape that measures in metres (for 3-B).
4. A kitchen scale that measures in grams (for 3-B).
5. A measuring cup that measures in millilitres (for 3-B).
6. Fraction manipulatives. The curriculum contains printables to make your own fraction manipulatives. The text uses visual pie models extensively, and students even learn to draw them for themselves in the exercises, therefore making or buying the manipulatives is entirely optional (optional; for 3-B).
